摘要: LVM(Low Volume Mister) is a dispositional technology of fogging in a limit closed space. It uses less water and generates the droplet. The system of LVM can spray agrichemical automatic, hence, can save many labor and wealth. However, it is rarely use in country because the choice of droplet distribution and the position of circle fan cann't fit in greenhouse. In the study, processing the effect of fan arrangement to the droplet distribution and the steam field by CFD, and attest the simulant result by fluorometer. Establishing the stimulant greenhouse which is fit in actuality, and divide into five cases of fan arrangement and LVM in the process. Analyzing the case in k-ε mode by CFD, then attest in actuality. After comparing the analysis of simulation and the result of actually experiment, the result of fan-arrangement in the end of the greenhouse is desirable. Therefore, it is feasible to forecast the effect of droplet distribution and fan arrangement.
LVM(Low Volume Mister)設備是用於有限密閉空間的一種噴霧技術,其顆粒微小,而且用水量節省,並且可以全自動的操作,不管是人力或者是物力上,都可以節省不少成本,但在國內的使用率卻不盡理想,主要是因為霧粒的分布與風扇位置的配置無法配合,在本研究中利用計算流體力學模擬軟體(Computational Fluid Dynamics) 進行風扇配置對風場與霧粒散布之影響,系統性分析後,最後再配合螢光劑施放後調查回收量分布的情形以驗證評估施噴效果。 實驗過程將風扇與LVM的配置分成五個部份,並建立與現場實際情形相符的模擬溫室,先利用CFD以紊流模式分析之,再做實際驗證,比較模擬分析與實際驗證的結果後,風扇配置於溫室底部形成對流的擺設之實際噴灑是比較理想的,而模擬分析的結果也是相同,因此,利用CFD預估LVM噴灑之霧粒與風扇配置的關係是可行的。
